This quadcopter is a home build by the man known as AliShanMao on YouTube and his website Only Flying Machines. As you can see, it is stripped back to just the essentials as this is just a prototype. A later video, included below, demonstrates it flying full payload weight of 2.3kg and it shows no signs of being any less agile because of it.

As you can see, this thing is fast and extremely agile. Both the main camera and the GoPro mounted on it demonstrate how rapidly it can climb, but also the level of control the pilot has over it as he circles the field. AliShanMao has also mounted two bright LED light units either side of the camera, so seeing it fly at night should be interesting.

AliShanMao isn’t happy building just one model of the Widow Maker, though. He’s also created a Baby Widow Maker, which should be better suited to navigating an indoor environment while retaining the agility of its big brother.

If you like what you see here, the good news is Only Flying Machines will happily sell you the kits to make your own. The Widow Maker models are listed as coming soon with no prices available yet. However, going on some of the other quadcopter kits he is selling you won’t see any change from $500.
